Exploration History

1940: Surface work performed on property. 1944: Craibbe-Fletcher Gold Mines incorporated to acquire property. 1945-47: Sylvanite Gold Mines and Rouyn Gold Mines optioned property. Magnetometer survey completed and approximately 50 holes drilled totalling 10,540 m. 1955: New Dickenson Mines assumed control of Craibbe-Fletcher, performed surface exploration, previous drilling was re-examined, and 6 holes were drilled totalling 1353.59 m. Horizontal drive from the 2050 ft level of Campbell mine extends 1475 feet into the property. 1958-61: 704.86 m of surface drilling, underground work from the 625.25 m level at Campbell consisted of extending a drive 450 m into Craibbe-Fletcher ground and 2507.1 m of underground drilling. 1982-83: Campbell Red Lake Gold Mines buys controlling interest, performs line cutting, surface work.

Geology Comments

Dec 07, 2005 (K R Kettles) - Most of the property is underlain by altered mafic metavolcanic flows. They are comprised mainly of massive basalts with two zones of strongly carbonatized breccia that are thought to be flow top material. A coarser-grained flow unit, locally called the Campbell Diorite , has been recognized on the property. Adjacent to Highway 125 a narrow band of pillowed flows extends across the property. In the northern part of the property, 2 bands of felsic volcanic rocks with associated bands of lean cherty iron formation are known to occur. The general strike in the area is about N70 degs W, and dips vary between 70 degs S to 75 degs S.

Mineralization

Mineralization Comments

Dec 07, 2005 (K R Kettles) - Ore grade values of gold occur in two parallel lenses about 30 m apart over a length of over 90 m. The southern zone is contained in mineralized cherty iron formation and silicified and carbonatized mafic volcanic rocks. The northern zone is situated in a run of silicified felsic volcanic rocks. Both zones strike at about N 70 degs W and dip 60 to 70 degs SW. Early drilling gave the following intersections for holes drilled at 30 m intervals (holes listed E to W): SOUTH LENS: DDH44- 0.42 opt Au at 45.75 m;DDH 50- 0.30 opt Au at 117.43 m; DDH43 - 1.24 opt Au at 59.48 m; DDH42 - 0.30 opt Au at 70.15 m; DDH38 - 0.415 opt Au at 79.30 m. NORTH LENS: DDH17 - 0.08 opt Au at 230.28 m; DDH44 - 0.07 opt Au at 79.30 m; DDH43 - 0.64 opt Au at 91.50 m; DDH42 - 0.17 opt Au at 88.45 m.

Alteration Comments

Dec 07, 2005 (K R Kettles) - The volcanic rocks have been carbonatized and silicified, and the iron formation contains sulphides.
